The focus of Dr. Yang's research is on dissecting and manipulating intracellular and intercellular signaling circuits governing feeding and anxiety-related behaviors in normal and obese animals using genetic and systems neuroscience approaches that include cell-type-specific electrophysiology, optogenetics, chemical-genetics, deep-brain measurements of neurochemicals, imaging, and behavior assays. One of the projects in Dr. Yang's laboratory is about synaptic and circuit rewiring in obesity. Obesity and its associated pathologies impose a huge burden to our society. Obesity may increase the risks of many other complications, such as type 2 diabetes and psychological disorders including anxiety. However, the mechanisms and the effective treatments of obesity and the associated disorders are largely unknown. It thus is critical to determine the cellular, synaptic, and circuit mechanism(s) underlying feeding and anxiety, providing apparent therapeutic targte(s) for the treatment of obesity, eating disorders, and anxiety.
In addition to neuroal regulations of energy states and anxiety, Dr. yang is also interested in studying the roles played by astrocytes in these regulations in both normal and abnormal conditions, including obesity and anxiety disorders.
